current port/package.

Fix build of www/otter-browser
The qmake port is required to be installed when compiling otter. While this
requirement is usually met due to its dependencies on qt5 elements which
depend on qmake, in case someone uninstalled qmake which is not a runtime
dependency for any qt5* port, otter would not build any more.
Resolve this introducing a dependency on qmake.

Update otter to beta 2. Patch qmake project file to pull in the QtConcurrent
module config, referenced by at least src/core/ContentBlockingList.cpp, and
track the dependency to it in ports, too.

Bump more ports that depend on libsqlite3.so:
- ports that set USE_SQLITE with the *_USE option helper
- ports that depend on libsqlite3 indirectly as reported by pkg rquery
